a situation in which something is so significant in greatness, that only the use of the words "awesome" and "fantastic" (combined with "ful") can be enough to describe the magnitude of its grandeur
Steven: Hey Jared. Did you go to that concert last night?
Jared: Yeah man. It was uber special awesomefultastic.
The word awesometastic is the cross, as we all know, of awesome and fantastic. But sometime this combination of words just isn't enough. thats when fucking comes in handy. Adding more feeling to the word we get awesome + fucking + fantastic getting awesomefuckingtastic
This cake is awesometastic vs. This cake is awesomefuckingtastic
A word created by an utter genius, meaning so awesome that awesome isn't a good enough word. You can also use the term 'awesomefully' which is even better than awesomeful. The best word ever created by humans.
